H3: retire manual harvest commands

Removes !forage / !mine / !scavenge / !fish / !essence / !commune from
the command surface. Typing one now returns a one-line deprecation DM
pointing at the auto-harvest flow ("Harvest is automatic now — just
walk."). The internal handleHarvestCmd / handleStandaloneHarvest paths
are left in place; operator deletes after soak per plan §H3.

Help text and the supplies-low autopilot pause line no longer mention
the manual verbs.
